Velocity magnitude control of maneuverable reentry warhead

In this paper, the kinematic model of reentry warhead was built to verify the effect of control law. Then, an idea velocity curve was designed to support a standard of velocity control and the calculation of attack angle and sideslip angle was discussed. Finally, the efficiency of control law was verified through simulation. The simulation result shows that the control law proposed in this paper can limit the velocity magnitude error within 10m without losing accuracy of control of fall point and velocity direction.
